; 1 Introduction Research on cathode materials of lithium-ion battery was mainly concentrated in the transition metal oxides of layered structure such as LiCoO2, LiNiO2, LiMnO2 and their derivatives. LiCoO2 is one of the first commercial lithium-ion battery cathode materials, but its application is limited because of the scarce cobalt resources, high prices and a certain degree of toxicity......
